I had been hoping to get down to my real goal weight by the end of the year but though I've lost good amounts the last couple of weeks, I also had some really low, slow weeks, and I'm not sure I'll get there so for the challenge I'll just aim to lose 21lbs. Goal weight for Christmas: 160lbs

Sounds good to me!! I'd love to be in the low 180's by Christmas....so I'll make my goal 180, so 31 lbs to lose starting today. I'm doing a new goal as of October 2nd, so my new goal is 170! I'm going to up it again as of November 6th...my new goal is 165 pounds by Christmas. This challenge has been awesome for me!

This is because when I started my weightloss, October 2002, I got within 16lbs of goal by October 2004. I began to wobble. I kept track, albeit a wobbling track, right up to Christmas 2004, when I was 168 and after that, kaboom. 25lbs would take me to 1lb better than that!
